Appendix Q: State By State

This is a work in progress as more jurisdictions and states are added as they adopt Appendix Q

List Of Municipality Or State That Has Adopted Appendix Q

Please due your own due diligence. If you see a state or county listed, check with your municipality to clarify that they have the same jurisdiction

Alaska: In Alaska the IRC is not adopted statewide. The “Deferred Cities” can adopt additional codes and some jurisdictions adopt the IRC and the IECC.

The IBC, IFC, IMC in Alaska are adopted by administrative rule making by the Alaska State Fire Marshal. The adopted code by state agencies are mandatory and fall under state inspection programs unless a local jurisdiction has been delegated by the code program as a “deferred jurisdiction.” When this occurs, the local jurisdiction administers and enforces their local program of the adopted state codes.

California: Mandatory Across All Local Government Jurisdictions: Effective January 1st, 2020

California Building Code Update (6/17/2019) – Appendix Q Tiny Houses: In recent discussions and emails with key staff of CA Department of Housing and Community Development (HCD), we have confirmed the following:
1) HCD has adopted the provisions of Appendix Q which will make its provisions MANDATORY across all local government jurisdictions.
2) We were able to confirm with HCD, that factory-built housing (FBH) next year can be built to CA Residential Code standards, inclusive of Appendix Q, (for units 400 sq. ft. or less).
3) Such FBH units built using Appendix Q standards would be permitted anywhere is California, subject of course to zoning codes.
4) The California building code update will go into effect January 1, 2020.

Background

For the past several months we have been quietly working with California Department of Housing and Community Development (HCD) and the Governor’s Office of Planning and Research (OPR) to ensure that provisions of the 2018 International Residential Code, including our tiny house Appendix Q code provisions, were properly implemented into the California Residential Code. Our concern was that we wanted Appendix Q code items for tiny homes to be, not only adopted by the state, but made MANDATORY in all of the 540 local government jurisdictions.

In past California code update cycles, the various Appendices were left as local option.Why is this important? One can only imagine the effort it would take to convince 540 cities and counties to adopt Appendix Q – a task which would take years to accomplish. Also, if Appendix Q provisions were not adopted across the board for all of California, it would be virtually impossible to factory build tiny house units for wide distribution.

Special Shout Out To Martin Hammer

A special shout out to Martin Hammer for, not only his work with Andrew Morrison in writing Appendix Q, but his efforts to stay on top of state bureaucrats to implement it properly in California.

Michigan: Appendix Q Is A Selected Option In ”Select IRC Options Use With The Michigan Residential Code”

The Home Builders Association of Michigan (HBAM) and the International Code Council (ICC) have joined forces to publish a targeted book of changes in the 2018 IRC to allow Home Builders Association of Michigan members and others to benefit from their new ability without having to buy the entire code. The book is titled ” 2018 Select IRC Options For Use With The Michigan Residential Code.”

Michigan Is Staying With 2015 IRC Until 2021 Is Adopted

The Flex Code Law, Public Act 504 of 2012 allows Michigan to choose to update the Michigan Residential Code every three or six years. Michigan chose not to update to the 2018 edition of the IRC published by the ICC and will be staying with the 2015 MRC until the 2021 edition of IRC is available and adopted.

Those issues include defining the very structures themselves: “The committee shall determine what constitutes a ‘tiny house,’ both on a permanent foundation and on wheels.”
Proponents of tiny homes say they can expand the state’s housing options by providing a relatively low-cost place to live that might help ease labor shortages and keep young adults in the state.

Ohio Adopted 2018 IRC: Did NOT Adopt Appendix Q

Personally spoke to the state of  Ohio- on July 25th, 2019 – They have adopted 2018 IRC – But have NOT adopted Appendix Q at this time. I spoke with Jay Richards and he explained that Ohio does not typically adopt an Appendix, they prefer to wait until it is written into the body of the model code. Their focus is on safety, sanitation and energy conservation. The state has no minimum square  footage requirement for a size of a home. It is possible to request a variance and local jurisdictions might have different size requirements for homes. The do not regulate tiny homes on a chassis.
